[RESOLVED] I so thought I had this but I don't - I am not creating multiple objects I don't thin

[gjon]

I thought I had two objects and that I was taking cups away from each of these two unique vendingmachine objects, called decaff and caffeinated. But after testing how many cups are left, I find that I am always having the same number of cups left in either object. Or whats happening is I have one object or maybe I am only accessing one of the two. I am not sure. I really need someone to explain to me what is going wrong with this.

I am trying to create two vendingmachine objects. Choose which one I want to buy from, then actually remove cups from that one as a cup of coffee is bought.

I am failing to somehow keep them seperate, create them properly or access them properly.

Any help would be so appreciated.

            VendingMachine Caffeine = new VendingMachine();
 
            VendingMachine DeCaff = new VendingMachine(10, .50);
 
            if (VendingMachine.Select() == 'c')
            {
                do
                {
                    Caffeine.Menu();
                } while (Caffeine.cupsCoffeeAvail > 0);
            }
            else if (VendingMachine.Choice == 'd')
            {
                do
                {
                    DeCaff.Menu();
                } while (DeCaff.cupsCoffeeAvail > 0);
            }
            else
            {
                Console.WriteLine("Invalid Choice");
                Console.WriteLine("So, because you tried to hack me:");
            }
            Console.WriteLine("I am sorry, but my machine is out of coffe cups. =(");
